Method and Apparatus for Performing Tile-Based Path Rendering

1. An apparatus for rendering an object including a path, the apparatus comprising: memory storing computer-executable instructions; one or more processors configured to execute the computer-executable instructions such that the one or more processors are configured to, obtain path data including information about vertices included in the path and a command corresponding to the path, calculate in parallel a final winding number of each of tiles included in a frame based on the path data, determine, for each tile, whether to perform shading based on the final winding number of the tile, and perform shading on each of pixels included in the frame based on a result of the determining.

2. The apparatus of claim 1 , wherein the one or more processors are further configured to execute the computer-executable instructions such that the one or more processors are configured to calculate the final winding number without rendering triangles including the object in a stencil buffer.

3. The apparatus of claim 1 , wherein the one or more processors are further configured to execute the computer-executable instructions such that the one or more processors are configured to: set a first winding number of each of the tiles included in the frame based on the path data; and calculate a second winding number of each of the tiles, through which the path passes, from among the tiles included in the frame based on the first winding number.

4. The apparatus of claim 3 , wherein the final winding number of each of the tiles, through which the path does not pass, from among the tiles included in the frame, corresponds to the first winding number, and the final winding number of each of the tiles, through which the path passes, from among the tiles included in the frame, corresponds to the second winding number.

5. The apparatus of claim 3 , wherein the one or more processors are further configured to execute the computer-executable instructions such that the one or more processors are configured to: assign an initial winding number to each of the tiles included in the frame; select tiles, through which the path passes, from among the tiles included in the frame; and update the initial winding number of each of the tiles located at one side of the selected tiles according to a shape in which the path passes through the selected tiles.

6. The apparatus of claim 5 , wherein the one side is determined according to a position of each of the tiles included in the frame and a position of the path in the frame.
